我试图使用Java和Microsoft SQL Server连接到本地sql服务器。 我正在使用sql server auth。无法使用java连接到sql server
下面的代码:
import java.sql.*;
public class Main {
public static void main(String[] args) {
String userName ="testlogin2";
String password ="pass";
String url ="jdbc:sqlserver://localhost/LabNoteMap;integratedSecurity=true;"; //LabNoteMap beeing target db
try {
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
Connection conn = DriverManager.getConnection(url, userName, password);
} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (SQLException e) {
e.printStackTrace();
}
System.out.println("end");
}
}
和堆栈跟踪:
"C:\Program Files\Java\jdk-9\bin\java" "-javaagent:C:\Program Files\JetBrains\IntelliJ IDEA 2017.2.5\lib\idea_rt.jar=63510:C:\Program Files\JetBrains\IntelliJ IDEA 2017.2.5\bin" -Dfile.encoding=UTF-8 -classpath C:\Users\Deus\IdeaProjects\testMYSQL\out\production\testMYSQL;C:\Users\Deus\Desktop\jdbc\sqljdbc_6.0\enu\jre8\sqljdbc42.jar Main
end
com.microsoft.sqlserver.jdbc.SQLServerException: The TCP/IP connection to the host localhost/LabNoteMap, port 1433 has failed. Error: "localhost/LabNoteMap. Verify the connection properties. Make sure that an instance of SQL Server is running on the host and accepting TCP/IP connections at the port. Make sure that TCP connections to the port are not blocked by a firewall.".

也有些SS:
另请注意,在Sql服务器配置中,tcp/ip已启用且端口设置为1433.
我猜可能是防火墙?但不知道如何检查它,或者别的什么?
检查你的防火墙,看是否有是关于什么应用程序试图连接到您的分区的一些日志记录 – Stultuske
您的URL无效,请检查[构建连接URL](https://docs.microsoft.com/en-us/sql/connect/jdbc/building-the -connection-url)的Microsoft网站上的SQL Server JDBC驱动程序文档。你错误地认为所有的JDBC驱动程序都遵循相同的URL结构,但它们不是。 –
